How to select and delete all the comments on a specific layer

[titeuf]

Situation:

Base layer has many various comments over some pages.
Layer 1 also has may various comments over some pages.

In the situation, I want to delete all the comment on the base layer, maitaining comments on Layer 1.

How can I do it?

What I tried so far is:
- Made layer 1 hidden.
- Selected all the comments and delete in the comment panel.
- This deleted all the comments including ones on Layer 1. <-- This is not what I want.

Hello titeuf,

I hesitate to write this because it is not a very smart way to do it, but the following steps are possible.

1. Display only the base layer you wish to delete comments.
2. Set zoom factor as low as possible in two-page continuous mode.
3. Use the Select Comment tool to select comments across multiple pages.
4. Delete the comment by pressing the Delete key, etc.

On a 4K monitor with 200% scaling, I could select up to 2,000 A4-sized pages. If multiple monitors are used in succession, the number of pages that can be selected can be increased by that amount. In fact, I confirmed that up to 8,000 pages can be selected with four 4K monitors vertically aligned.

Thank you very much. I am sure this works very fine.
As you said it is not smart way. I think it will be better if in the comment panel we could select comments by layers or identify which layer they belong to.
Anyway your solution inspire me to zoom out to select all comments. Thanks again. It is very helpful.
